Gestational Diabetes

3 weeks ago I had my glucose test which was elevated. I've been checking my fasting sugar and also an hour after each meal I check my sugars. My fasting checks are always between 70-90 (they want them under 100) while my hour after I eat sugars are anyway from 100-140 (they want those under 120). I watch my carbs, I eat protein, I haven't seen a brownie in weeks. Today the dietary lady calls to tell me I will be referred to an endocrinologist. I'm terrified.
